Serial No. 649,795.

T 0 all whom it may concern.-

Be it known that I, JOHN CHRISTENSEN, a citizen of the United States ofAmerica, residing at Evans City, in the county of Butler and State ofPennsylvania, have invented certain new and useful Improvements inTrolley-Wire Hangers, of which the following is a specification,reference being had therein tothe accompanying drawing.

This invention relates to a trolley wire hanger, and the object of myinvention is to provide a positive and reliable means, in a manner aswill be hereinafter set forth, for supporting a trolley relatively to ahanger wire.

My invention aims to provide a sectional hanger that can be easily andquickly clamped upon the hanger wire for firmly supporting the trolleywire. The hanger has been designed for a single trolley wire or a doubletrolley wire, and, the construction of the hanger is such that it can beeasily manufactured at a comparatively small cost and is easilyinstalled.

The invention further aims to accomplish the above results bycombination of elements that will be hereinafter specifically describedand then claimed.

Reference will now be had to the drawing wherein there is illustratedthe preferred embodiment of the invention, but it is to be understoodthat the structural elements are susceptible to such variations as fallwithin the scope of the appended claim.

In the drawing; Figure 1 is a front elevation of a single hanger. Fig. 2is a longitudinal view of the same. Fig. 3 is a front elevation of adouble hanger partly broken away and partly in section. Fig. 4 is across sectional view taken on the line IVIV of Fig. 1. Fig. 5 is a planof a portion of the lower section of the hanger and Fig. 6 is a plan ofa portion of a double hanger.

A single hanger in accordance with this invention includes asubstantially U-shaped body provided with a pair of diametricallyopposed extensions, each of which is formed with a longitudinallyextending groove of a length equal to the length of its respectiveextension. The body portion 1 further includes a vertically disposedcentral hub 3 having its upper face provided with an annular recess atin which is mounted a split locking washer 8, the opening 7 of thelatter alining with an opening 9 formed in the hub 3. The body 1 istermed the lower member of the hanger. The hanger further includes anupper member consisting of a body portion 10 and a pair of oppositelydisposed arms 11. The body portion 10 conforms in contour to the shapeof the hub The upper member is mounted upon the lower member and thebody portion 10 is positioned in alineincnt with the hub 3. The bodyportion 10 is formed with a socket 14: which is in alinement with theopenings 7 and 9. The upper member has its lower face formed with alongitudinally extending groove 12, which extends from one end to theother end of said member and which has its central portion offset withrespect to the socket 141, as clearly illustrated in Fig. 5 of thedrawings, and which is indicated by the reference character (3.Offsetting the groove in the manner as stated, a clearance is providedfor the stud bolt 15, when the hanger wire 13 is mounted between saidmembers. The said bolt 15 extends forwardly through the openings 9 and 7and engages in the socket 14;. n

The shape of the body 1 and extensions 2 with respect to the arms 11 issuch as to provide an opening which is filled by the hanger wire 13, asclearly shown in Figs. 1 and 2. The hanger wire 13 is mounted in thegrooves 5 and 12, as well as extending through the offset portions 6 ofthe groove 12 and is clamped between the upper and lower members of thehanger through the medium of the said bolt 15 and locking the washer 4.The lower end of the bolt 15 is detachably mounted in a head 16 whichterminates in a gripping member 17, the latter cooperates with agripping member 18 for holding a trolley wire 19. The member 18 isriveted or otherwise connected, as at 20, to the member 17. The groovesin the extensions 2 are formed by the longitudinal ribs 21, these latterare overlapped by the walls of the groove 12 when the upper and lowermembers of the hanger are clamped together. The body 1, as well as eachof the extensions 2, is reinforced through the medium of a web 22.

In Figs. 3 and (3 of the drawing there is illustrated a double hangercomprising a longitudinal body 23 having bosses 24 and extensions 25 atthe ends of said body. The bosses 2 1 accommodate split washers 26 andbolts 27, the former retaining the hanger wire 28 in engagement withmembers 29 that are retained upon the body by the bolts 27.

The bolts 27 are similar to the bolts 15. The top of the body 23 has alongitudinal rib 80 that retains the wire 28 at one side of the bolt 27.

The hanger in its entirety can be made of light and durable metal, andit is apparent that the trolley wire can be detached from the hanger ordetached from the hanger wire without lowering or detaching the ends ofthe hanger wire.

What I claim is z- A trolley wire hanger comprising an upper and lowermember one overlapping the other, said lower member including a hub foran opening extending entirely therethrough and further provided in itsupper face with a recess with which the upper end of the openingcommunicates, a split washer mounted in said recess, said lower memberfurther provided with a groove, said upper member having a verticalsocket opening at through said washer and engaging into said socket forclamping the two members together thereby maintaining the wire inposition, and means carried by the lower end of said bolt for supportinga trolley wire.

In testimony whereof I afliX my signature in the presence of twowitnesses.
